Li Zhongqin;Li Xiaoli;Lingtai Agricultural Technology Promotion Center;
Film technology is a set of multiple cropping of winter wheat yield and cost, environmental protection,preservation of the membrane after maize harvest, new technology as a whole. In order to show the promotion of this technology, the film technique of winter wheat cropping demonstration reserve agricultural technology promotion center in Gansu County of Lingtai Province set up the whole film after maize harvest. The demonstration results show: the demonstration field the field is increased by 378.5kg/hm~2, compared with the conventional cropping technology by895.5kg/hm~2, saving 150 yuan /hm~2, this technique has reduced the amount of labor, reduce investment, improve the yield effect, with the promotion of significance.
